Appiicauon inea Aprire, 1922. sei-iai No. 550,768.

10 @ZZ/whom t may concern Y Be it known that T., GiLBnRT' C. Pr-iLEGnn, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in l/Vrenches, of which the following is a specification.

This invention relates to improvements in wrenches.

The primary object of the invention is the provision of a wrench which may be quickly adjusted, in order that the same may be selectively used for gripping plane or arcuate surfaced articles.

A further object of the invention is the` provision of a wrench including fixed and sliding jaw structures, and in which the sliding jaw structure may be quickly adjusted with respect to the fixed jaw structure.

A further object of the invention is the provision of a wrench jaw primarily adapted for use in connection with the gripping of plane surfaced articles, but which includes a novely arrangementso thatl the wrench jaw may have an auxiliary gripping element extended outwardly with respect to the article gripping'face of said jaw, in order that said auxiliary gripping member may be utilized in connection with said jaw to engage round surfaced articles, such as pipes. i

A further object of the invention is the provision of a wrench embodying the above mentioned characteristics, so that the article engaging surfacesrof the jaws upon said wrench may be normally positioned in parallel relation, for the gripping of polygonal shaped articles, such as nuts; said wrench furthermore including improved auxiliary means for riding outwardly of the plane of said article engaging surfaces of the jaws, and whereby the wrench may be utilized for gripping pipes and the like,

much in the same manner as the ordinary` a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a fragmentary'side. elevation, i,

of portions of the improved wrench, show-l ing the samein a differently adjusted position than that illustrated in Figure 1.`

Figure 3 is a side elevation of the head portion of said wrench, showing the fixed and sliding jaws thereof-in abutting relation. y

Figure 4t is anedge elevation of the iin,- proved wrench `structure as illustrated in Figure 3. f Y v Figure 5 is a transverse cross sectional view taken on the line 5 5 of Figure 1.

Figure G vis a transverse cross-sectional view taken on the line 6-6 of Figure 1.

Figure 7 is a cross'sectional view taken on the line 7 7 of Figure 3.

In the drawings, wherein for the purpose of illustration is shown the preferredeinbodiment of my invention, the letter A des ignates the improved i quick adjusting wrench, whichcomprises a supporting sliaiilrlO; fixed jaw 11; sliding jaw 12; auxiliary grip devices 13 andlll for the fixed and-sliding jaws respectively; and locking arrangement 15 for connection of the slid-ing jaw 12 in different positions up-n on the shank 410.

The shank 10 is substantially rectangular As can readily be seen from' Figure 4i' of the drawings, the head or fixed jan7 11. is of greater width than the width of ythe shank 10, extending outwardly upon both sides thereof, one of the extending sides` being, in fact, a cover 2O which is. secured as by rivets orrother elements 21 to the head portion 22 of the fixed jaw 11, so that the auxiliary grip 13 to be subsequently described may be properly housed in the said ioo I relation to thelaterally CII jaw l1; The opposite end of the shank l0 is preferably provided with a lrnob 25 ei;- tending laterally thereot', whereby the sliding jaw l2 inay be properly affixed to said Vshank 10 against liability ot accidental dis-k placement. 'llhe sliding jaw structure l2 is relatively longer than tle jaw structure 11, since the lsaine is adapted for housing both the auxiliary gripr means Ul and the locking means l5. This jaw l2 preferably comprises a body portion 29 having the rectangular shaped groove 30 extending longitudinally thereof` and adapted tor, snug sliding reception ofthe shank l() therein. A coverA 3l is provided tor clamping over that side ot the body portion 29 in which the groove 30 is formed, in order ythat the groove 30 rnay forni a pocket in which the shank 10 rnay slide. This cover 3l inay be maintained in proper relation upon the body portion 29 as by rivets 32. A portion 35 of the sliding jaw structure l2 extends laterally oi" the shank l0 al d in operative l extending portion 17 of the lined jaw structure ll.. in article engaging tace 36 is provided upon this portion 35, Which lies in plane substantially at right angles to the longitudinal extension ot the shank l0. Thus, the article engaging faceslS and of the lined and sliding avv structures respectively, are in parallel relation, and in tact, so related es to be in facing cooperation tor receiving nuts, pipes and other articles yto be gripped.

Referring to the lockingY nieans l5, the saine includes a Wedge shaped ineniber 4:0 slidable iny a groove il tornied inwardly froin the saine side of the sliding aw body 29,7in which the shank groove 30 is formed,

Vthis groove lil in tact, deiining a taper surface against which the Wedge ltOroperates, so that one side 4t2 of the Wedge Ll@ is norinally inparallel relation with a marginal edge or theshanlr 10. A spring e8, preterably of the coinpi'e'ssible type, is disposed Within apocket 4lof the *sliding jaw body 29', one end ot said` spring engaging the enlarged edgeV of the Wedge ineinber all), whereby the latter is norinally forced upwardly in its groove ill, so thatits sur-tace 42 is forced into snug engagement against the shank l0E Thus, it can be seen that this action of the Wedge i0 against the shank l0 will have a tendency to, iirinly loci; the sliding jaw structure l2 toV the shank l0., A, pocket or recess Lloris Qtfo ned inwardly trono the rear ot thesliding j 'avvy i2, having a leverrl pivotally connected as by a rivet vStorthe body and vcover portions of the sliding structure l2, so that 'an inside ended) of the lever i? is disposed adjacent the reduced 'end 5G of the Wedgerineinber e0. This reduced end ,50 ot the Wedp niernber 40 normally ,xte'hdsntej'he r0.0 @t e5, S0 that tft/Then the lever 47 is rocked by an operator, the inside edge 49 thereof inay engage he end 50 of said Wedge, so that the saine may be depressed against the action ot the spring 46, to release the saine from binding engagement against the shank. Y rllhe operation of this locking mechanism 15 is obvious troni the construction illustrated in Figure l ot the drawings.

The auxiliary gripping device 13 coinprises a grip nieinber 52 Which is pivotaily connected as by a pin 53 Within a recess 5e formed in the head portion 22 of the tixed jaiv ll', said recess preferably being open upon the face 18 of the jan' structure l1, so that theuinember 52 may be rocked outwardly troni the plane defined by the tace 18. rthe.marginal edge of the grip ineinber 52 is preferably provided With a series of teeth 55, Which when the nielnber 52 is snugly Within its pocket recess 5e ivill be disposed inwardly of the tace 18, so that they will not interfere With any article being gripped upon the race 18. However, when the ineinber is rocked outwardly from the lined portion 17 ot the jaw il, the teeth 55 Will be extended outivarcly olZ the same. Since the pin 53 pivots the niember 52 upon an end thereof adjacent the shank l0, it can be seen that the forward end or the inelnber 52 is capable or the greatest extension outwardly troni the taco Since the teeth 55 are in rack torination, it obvious that the` plane in' Which they lie will dei/ine an article engaging por-- tion or surface which is disposed in a plano at an acute angle ivith respect to the plano defined by the a ticle engaging surface i8. A lug operating Within a grooml `liinits the extension ot the grip nieniber 52 roin the jaw il spring 59, pieferibly of the tifr4 type, is aiiiiled in the poeh t or recess 54 or the jaw head portion 22, so that the forward end thereof engages a pin (ffii aiii'xed in the auxiliary grip-member 52, said spring 59 being normally under 'a tension to maintain the grip ineniber 52 in the poclot 5ft., so that the teeth 55 thereof lie inwardly troni the article gripping surtace i8. cain lever 63 is pivoted in the pocket 5e, as by pins 65, which entend transversely of the jaw structure lls l lmob 66 is formed upon the outer end one jot the pins G5 and extends fron; the' out ltace or the structure ll, for gageinent, whereby 7When the sain lated, the lever 63 may be throv: Y ,l cani action upon the g l ineinber forcing the saine outwardly troni "le il, as hereinbefore describen. This lever 63 4crc-acts against an abrupt shoulder 66. formed in the nie'nibei 52, `whereby said grip ineniber vvhen in its ezlrtended position may be securely braced against the lever 63 for article gri "sing purposes;

Liary gripping device 1i as carried upon the sliding jaw1 29, from the article gripping face 36 the-reof. The lower surface 72Vof this pocket 71 is inclined, in converging relation, with respect to the article gripping surface 36, so that said pocket decreases in depth from the outer end of the jaw portion 35 towards the shank `groove therein. The grip member 70 is provided :with a. series of teeth 73 thereon, arranged in rack likeforrnation. The lower surface or marginal edge 74: of this grip member 70 which lis opposite to the plane in which the. teeth 73 lie is formed in tapering relation with respect to the plane in which said teeth 73 are disposed, said-surface 74, in fact, being provided for sliding engagement upon the pocket surface 72 and having guide ianges 82FL thereon operating in lateral grooves 83a. A flexible spring 76, preferably of the flat type, is carried in a groove 77 of the sliding jaw 12, normally having an end thereof cooperating against the grip member 7 O to force the same away from the shank receiving groove 30, substantially as is illustrated in Figure 1 of the drawings. lVhen the gripping member 70 is in this position, the teeth 73 lie inwardly from the plane defined by the article engaging face 36 of the wrench structure 12, so that when said sliding jaw structure 12 engages a nut or pipe, the teeth 73 will in no wise interfere with suoli action. In order to effect a manual operation of the auxiliary grip member 70, a pin 79 is oscillatively mounted transversely of the sliding jaw 12 and in the laterally extending portion thereof, said pin 79 having a knob portion 80 thereon, which extends from a side of the jaw structureV 12 altogether similar to the extension of the knob 66 above described. A stem 81 is radially disposed upon the pin 79 adapted for engagement against a. shoulder 82 formed inwardlyfrom the inclined surface 74, so that upon oscillation of said pin 79, the stem 81 thereof will engage said shoulder 82 for sliding the member 7 0 upwardly upon the inclined surface 72, and whereby the teeth 73 may be extended outwardly of the plane defined by the article engaging surface 36, and substantially as is illustrated in Figure 2 of the drawings. j

In operation, for the adjusting of polygonal shaped articles, such as nuts, bolts heads, and for the holding of other plane surfaced articles, the auxiliary gripping devices 13 and 14 will be so arranged in their respective jaw structures that the teeth'55 and 73 thereof will not extend `from the article engaging surfaces 18 and 36. In'this manner, the fixed sliding jaw structure 12 kmay be adjusted upon the shank 10, sothat the surfaces 18 and 36 may engage the sides of a nut or other article, having relatively flat surfaces, and upon releasing ofsaid lever 47,- the sliding jaw structure 12 will. lock,

whereby the wrench A maybe used for -adjusting purposes. On the other hand, if it is desired to hold pipes, or adjust couplings or other articles having arcuate surfaces, it willbe desired to use the wrench A much in the same manner as the ordinary pipe wrench is used. To thisend, the auxiliary gripping members 52 and 70 are so adjusted in their respective aw .structures 11 and 12 that the teeth 55 and 73 thereof will beextended from the article `engagingsurfaces 18 vand ln this position, it is to be noted that the plane in which the teeth 55 lie is at an acute angle to the longitudinal extension of the shank 10. On the other hand, the plane in which the teeth 73 lie is substantially at right angles to the longitudinal i extension of the shank 10. Thus, a pipe or other similar article may be gripped by adjusting the jaw 12 so that the same is engaged by kthe teeth -55 and 73, and upon locking of the sliding jaw structure 12 upon or other article may be held or adjusted as desired.

From the foregoing, Vit can be seen that a wrench has been provided, which is an extremely useful device, in that the saine can be quickly and conveniently adjusted. The toothed gripping members 52 and 70 will hold their extended positions notwithstanding the springs 59 and 76 co-acting thereon, since said springs are only provided for return of their grip members when an operator has properly adjusted the knobs 66 and 80. Thus, the wrench may be utilized for various purposes. It is to be noted that lateral extensions 90 and 91 are provided upon the fixed and sliding jaws respectively, which extend outwardly thereon opposite to the Varticle engaging portions above described, said portions 90 and 91 having the surfaces 92 and 93 respectively.

the shank 10 as above described, the pipev Various changes` in the shape, size and arrangement of parts may be made to the' 'form of the invention herein shown and described, without departing frorn the' spirit of the invention or the scope of the claims.
